The high specific capacity of transition metal sulfides (TMSs) opens up a promising new development direction for lithium-ion batteries with high energy storage. However, the poor conductivity and serious volume expansion during charge and discharge hinder their further development. In this work, trimetallic sulfide Zn–Co–Fe–S@nitrogen-doped carbon (Zn–Co–Fe–S@N–C) polyhedron composite with a core–shell structure is synthesized through a simple self-template method using ZnCoFe–ZIF as precursor, followed by a dopamine surface polymerization process and sulfidation during high-temperature calcination. The obvious space between the internal core and the external shell of the Zn–Co–Fe–S@N–C composites can effectively alleviate the volume expansion and shorten the diffusion path of Li ions during charge and discharge cycles. The nitrogen-doped carbon shell not only significantly improves the electrical conductivity of the material, but also strengthens the structural stability of the material. The synergistic effect between polymetallic sulfides improves the electrochemical reactivity. When used as an anode in lithium-ion batteries (LIBs), the prepared Zn–Co–Fe–S@N–C composite exhibits a high specific capacity retention (966.6 mA h g−1 after 100 cycles at current rate of 100 mA g−1) and good cyclic stability (499.17 mA h g−1 after 120 cycles at current rate of 2000 mA g−1).

A novel solution has been proposed in this study to address electrode chalking and capacity degradation issues associated with transition metals as anodic materials in Li-ion batteries. The new strategy is based on constructing nitrogen-doped carbon shell-covered transition metal nanoparticles. In this study, the design of onedimensional nanotubes and the introduction of nitrogen atoms improve electronic conductivity and electrode integrity and also provide abundant active sites for lithium-ion battery reactions. In the first step, carbon-coated NiCo compounds were synthesized by using acetate ions as the carbon source and Ni and Co as the metal sources. Subsequently, nitrogen-doped carbon CNT-encapsulated NiCo nanoparticles (NiCo-N-C-1, NiCo-N-C-2, and NiCo-N-C-3) were successfully prepared by utilizing the precursors from the first step and using melamine as the nitrogen source for introducing nitrogen atoms. The unique one-dimensional nanotube structure of NiCo-N-C-2 anodes demonstrated a discharge capacity equal to 639.4 mAh g −1 following 300 cycles at a current density (I d ) equal to 0.5 A g −1 with an extended reversible capacity equal to 442.5 mAh g −1 following 1400 cycles at I d = 2 A g −1 , demonstrating the potential application of NiCo-N-C-2 nanotubes in Li-ion batteries with a high power density and an extended cycle life. Moreover, as it was coupled with the LiFePO 4 cathode, the prepared Li-ion full cell demonstrated a capacity retention equal to 91.4% following 500 cycles at I d = 1 C (0.1 C=170 mA h g −1 ), further highlighting the high capacity, excellent multiplication, and cycling performance of the NiCo-N-C electrode. This simple synthesis strategy offers a new approach to fabricating high-performance carbon and nitrogen-clad metal particle composites with promising applications in various energy-related fields.

The lack of high‐performance electrodes is a key factor restricting the development of sodium‐ion batteries (SIBs), and usually a certain type of electrode material alone often fails to combine the merits of high capacity and good conductivity. Herein, nitrogen‐doped carbon (NC) was used as a multifunctional bridge to uniformly compound high‐capacity MoS2 nanoparticles with highly conductive Ti3C2Tx nanosheets to form Ti3C2Tx@MoS2/NC composite with flower‐like architecture. Ultrafine MoS2 nanoparticles were uniformly anchored on Ti3C2Tx nanosheets to form nanosheets primary building blocks with a sandwich‐like architecture, which not only shortens the ion transfer distance but also enlarges the layer spacing of Ti3C2Tx favoring the storage of more sodium ions as well as their transport capacity. Moreover, the flower‐like structures with abundant edges can provide an ample active sites and high pseudocapacitance behavior. As a result, flower‐like Ti3C2Tx@MoS2/NC displays a high electrochemical properties with an excellent cycling stability over 2000 cycles (81.4 % capacity retention) and preeminent rate capacity of 383 mAh g−1 at 30 A g−1. Furthermore, Ti3C2Tx@MoS2/NC‖Na3V2(PO4)3 full cell displays a capacity of 59 mAh g−1 at 0.4 A g−1 after 180 cycles. This work displays a high‐performance anode composite for SIBs and provides insight into the preparation of other composites.
